Amid the growth of Tasmania’s wind farming business, researchers have warned hundreds of turbine blades might find their way into landfills until end-of-life applications are established. That’s in accordance with brand new research from the College of South Australia, which highlights the challenges of recycling the blades and warns Australia is dealing with a rising pile of wind farm waste.

Amid the growth of Tasmania’s wind farming business, researchers have warned hundreds of turbine blades might find their way into landfills until end-of-life applications are established.
 
That’s in accordance with brand new research from the College of South Australia, which highlights the challenges of recycling the blades and warns Australia is dealing with a rising pile of wind farm waste.
 
In North-West Tasmania alone, no less than 11 wind turbine farms have been constructed or are in development, all of which will someday face the issue of piles of big, decommissioned blades.
 
And it’s no small feat – on the West Coast, for instance, there are 31 turbines spinning at Granville Harbour.
 
Every turbine has three blades measuring about 62 metres in size – longer than the wing of a Boeing 777.
 
The research, led by Professor Peter Majewski, explains that the blades are often fabricated from both carbon fibre or or glass fibre composite materials, each is costly to break down and have minimal market worth.

Amid the growth of Tasmania’s wind farming business, researchers have warned hundreds of turbine blades might find their way into landfills until end-of-life applications are established.

And it’s no small feat – on the West Coast, for instance, there are 31 turbines spinning at Granville Harbour.

The research, led by Professor Peter Majewski, explains that the blades are often fabricated from both carbon fibre or or glass fibre composite materials, each is costly to break down and have minimal market worth.
 
“The identical options that make these blades cost-effective and dependable to be used in industrial wind generators make them very troublesome to recycle in an economical way,” Professor Majewski stated.
 
With estimates of world waste generated by wind turbines estimated at over 43 million tonnes by 2050, a world-wide race is on to find viable options . Some European nations have already banned the dumping of used blades in landfills.
 
OPERATORS OR MANUFACTURERS?
 
In Australia, Professor Majewski believes the price of recycling the blades in comparison with the low worth of the recovered materials makes it unrealistic to anticipate a market-based recycling answer to emerge.
 
This means that both producers and wind farm operators will be left bearing the cost of disposing of the blades from their operations, which might then be handed on to others.
 
David Pollington is the chief working officer for UPC Renewables Australia, a company with plans to construct as many as 122 wind turbines on Robbins Island.
 
He stated the difficulty of disposing of material had been a consideration within the 30 years he had worked in the energy business, from batteries to tyres to {solar} panels.
 
“It’s now one of many extraother issues for us, out of all of the issues we must deal with,” he admitted.
 
“We’ve had a couple of folks asking about it in our meetings, which I see as positive.”
 
The effort continues to be within the approval stage, and Mr Pollington stated UPC has not decided on the turbines it will use and does not know what conditions are likely to be included with any permit issued.
 
He stated the company was working on methods to make its entire operation sustainable, and that others had been doing the same.
 
Amongst these is Denmark-based wind turbine producer Vestas, which provided generators to Granville Harbour. The company, in 2020 dedicated to 100 per cent recyclable generators by 2030.
 
Mr Pollington stated it was a part of a broader push away from landfill, which UPC would take into account whether or not it was a condition of approval. 
 
“Beyond wind turbines, I’m speaking about every part we use … it’s a little bit of an interest of mine. After we purchase a bit of furnishings, are we pondering its end of life. What occurs to it as soon as its completed?” he requested
 
“Consider what number of tyres there are in landfill for the time being. Or finite assets in sensible telephones – it’s irresponsible to place that in landfill, and never economical.
 
“One of many beauties about all this is that … with generators, we’re not discussing a few dangerious drawback. There’s a little bit of petroleum within the gearboxes, however all the opposite bits are inert supplies.”
 
CONSUMER COST
 
The common lifespan of a wind turbine lies someplace between 20 and 30 years.
 
For Professor Majewski, one of many necessary elements in ensuring there’s sufficient money available for these blades to be disposed of even when producers disappear or wind farms go broke within the meantime.
 
He stated it was seemingly energy buyers could bear the end-of-life price via energy tariffs, however he remained hopeful that market competitors between energy producers would assist to minimise the influence.
 
“There shall be some price to this for everybody concerned, however we have now to simply accept that as a part of the price of producing energy on this means,” Prof Majewski stated.
 
“Without such options, energy choices like wind and {solar} might show to be no more sustainable than the previous energy sources they’re aiming to replace.”
 
Mr Pollington largely agreed that the price of recycling supplies would seemingly be handed to the developer.
 
“One factor which is admittedly troublesome to undestand is that there's a price to each resolution,” he stated.
 
“However I feel in the end persons are pleased to pay additional for greener energy and to know that there’s an end-of-life course.”
